RAT-POISONING DEVICE.

To all whom it may concern:

Be it known that I, GROVER G. MAGNESS, a citizen of the United States of America, residin at Sardis, in the parish of Sabine, and tate of Louisiana,.have invented new and useful Improvements in Rat-Poisoning Devices, of which the following is a specification.

This invention embodies improvements in fumigators and more particularly relates to a rat poisoning device.

It is the principal aim and object of the present invention to provide a device of the above character designed for accommodating a chemical solution the fumes of which issue therefrom and mingle with the atmosin which the device is mounted for exterminating 0r poisoning rodents which inhale the fumes.

It is an equally important object of the present invention to provide a device of the above mentioned character designed to be mounted in the grain in a grain bin or the like and provided near its lower end with perforations through which the poisonous fumes will issue and permeate the grain without in any way injuring the grain but serving to poison any rodents that inhale the same. A

As a further improvement the present invention contemplates the provision of a device of the above character wherein improved absorbent means is mounted Within the supporting casing and saturated with a poisonous solution the fumes of which are prevented from escapin from the casin except through the speciafiy provided per orations.

It is a more specific object of the present invention to provide common means for mounting the absorbent means and for supporting a closure stopper for the top of the casing.

It is an additional object of this invention to provide a device of the above mentioned character which is simple inconstruction, thoroughly reliable and efficient in its purpose and inexpenslve in manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, the combination of elements and the arrangement of parts which will be amplified in the construction hereinafter described and the scope of the Patented Jan. 28, 1919.

Application filed January 9, 1918. Serial No. 211,030.

application of which will be indicated in the appended claim.

The invention is clearly illustrated in the accompanying drawing, in which 2-- t Figure 1 is a vertical section of the inven- Fig. 2 is a perspective detail of the supporting rod;

Fig. 3 is a perspective detail of the casing.

Similar characters of reference are employed in all the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawing, there is provided a supporting casing 1 preferably of a tubular configuration the lower end being closed and pointed as indicated by the numeral 2 to facilitate the penetration of the device in a pile of grain, not shown. The casing is provided near the pointed end with spaced rows or circles of perforations or openings 3 for a purpose that will hereinafter appear while the upper end is open and flared outwardly as indicated by the numeral 4.

A stopper 5 formed desirably of cork or other suitable material is mounted in the open upper end 4: and serves to removably close the casing.

As intimated, improved absorbent means have been provided and in reducing this feature of the invention to practice a sponge 6 is employed and is preferably of a cylindrical configuration being provided on its outer surface with an annular groove 7 designed to be positioned opposite the circles of openings 8. By this arrangement when the sponge 6 is saturated with a suitable solution, the major portion of which is carbon sulfid, the fumes will congregate in the grooves and issue through the openings 3 and enter the grain adapted to be disposed about the sides of the casing. This solution is' prepared so as not to have any injurious effect on the grain yet at the same time it will serve to poison rats or other rodents that eat or otherwise destroy the grain.

lVith a view toward providing common means for supporting the sponge 6 in a proper position in the casing and for facilitatmg the removal of the stopper an elongated rod 8 is employed and is formed on its lower end with a loop 9 which serves as a stop for the sponge 6 when the latter is anchoredon the rod. The rod is also bent to provide another loop 10 which is positioned near the upper edge of the sponge to hold the latter against accidental vertical sliding movement on the rod. Near the top of the rod a further stop loop 11 is formed and this loop 11 serves as a support for the stopper 5 which when the upper end of the rod is passed vertically and centrally through the stopper the upper end of the rod is bent to form a finger ring 12 which facilitates removal of the stopper and also the sponge. The extreme terminal of the rod is twisted about the main portion and serves as a stop to cooperate with the stop loop 11 in limiting vertical sliding movement of the stopper.

In use, the casing l is adapted to be inserted in the grain in the grain bin whereupon the finger ring 12 is engaged and lifted upwardly so as to remove both the stopper and the sponge which latter is saturated with a poisonous solution and again inserted in the casing so that the groove 7 will be positioned opposite the openings 3. At the same time the stopper 5 is inserted in the upper end to close the same to prevent fumes from escaping at the upper end of the casing to assure of the fumes issuing through the openings 3.

It is believed that in view of the foregoing description, a further detailed description 'of the operation of the invention is entirely unnecessary. Likewise it is believed that the advantages of the invention will be readily apparent. 7

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof and it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limited sense. It is also to be understood that the language used in the following claim is intended to cover 'all the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is A device of the character described including a tubular casing having the lower end closed and pointed and the upper end open and flared outwardly and provided near the lower pointed end with circles of perforations, a rod, an absorbent member of a cylindrical configuration anchored upon the lower end of the rod for insertion within the casing and formed with an annular groove designed to be positioned opposite the openings, a stopper carried near the upper end of the rod and positioned to seat against the open end of the casing for closing the casing at the time the groove is positioned opposite the openings, and a handle formed on the upper end of the rod for facilitating removal of the rod and consequently the stopper and the absorbent member.

In testimony whereof I afliX my signature.

GROVER C. MAGNESS.
